Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] A method for hoisting a web of a wind turbine blade in this embodiment includes:

[0024] Step S1, such as figure 1 As shown, after the web is removed from the mold and repaired, start from the positioning length of the web in the mold at 4m, and fix a U-shaped block at a predetermined distance in the length direction to ensure the predetermined area in the length direction of the web (that is, in the The width of the inner gap between the leading edge web ...

Abstract

The invention relates to the technical field of wind power generation, and discloses a wind turbine blade web plate hoisting method. The wind turbine blade web plate hoisting method comprises the following steps: S1, after a web plate is demolded and shaped, fixing a U-shaped block from the locating length of 4 m of the web plate in a mold along the length direction at a preset distance; S2, before the web plate is hoisted, selecting hoisting tools matched with the width size of the inner layer according to the widths of gaps between the inner sides of front edge web plates and rear edge web plates, which correspond to three regions, i.e. the blade root, the blade body and the blade tip, of the web plate; S3, mounting the hoisting tool in the blade root region corresponding to the web plate; S4, repeatedly performing the step S3 on the blade body and the blade tip regions corresponding to the web plate so as to mount the hoisting tools in the blade body and the blade tip regions; S5, fixing the three hoisting tools on a travelling crane, and hoisting the web plate to an adhesion region through the travelling crane; and S6, after the web plate is placed on the shell, taking down the hoisting tools. Compared with the conventional method for hoisting the web plate in a binding manner, the wind turbine blade web plate hoisting method has the advantages that the labor intensity of an operator is alleviated, the production efficiency is improved, and the product quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of wind power blade manufacturing, in particular to a method for hoisting a wind power blade web. Background technique [0002] Wind power blades are the core components of the unit, and wind power blade technology is one of the core technologies of the wind power generation system. It is mainly composed of the suction side (SS) shell of the blade, the pressure side (PS) shell and the web through adhesive bonding. The web includes a leading edge web and a trailing edge web symmetrically arranged therewith. Web hoisting is the first step in bonding the web structure to the shell, and the hoisting method determines the quality of the web and the production efficiency of subsequent blades. [0003] The traditional web hoisting method is to use straps to lift the web from the SS adhesive surface and then fix it with the truck for transportation. After hoisting to a suitable position, pull out the straps. This ...
